LUCIUS EJIRUESDELL, OF BRISTOL, NEW HAMPSHIRE.

RAI LWAY' SNOW-PLOW.

SPECIFICATION forming part of Letters Patent No. 406,117, dated July 2, 1889.

Application filed September 28, 1888. Serial No. 286,661. (No model.)

To all whom/ it may concern.-

Be it known that I, LUCIUS E. TRUESDELL, of Bristol, in the county of Grafton and State of New Hampshire, have invented new and useful Improvements in Railway Snow-Flows, of which the following is a specification.

This invention relates to that class of railway snow-plows or track-clearers in which the mechanism for removing the snow and ice from the track is operated by power supplied by an engine which is made a part of or carried by the carriage which supports the plow, or by power supplied by the locomotive. As the engine or locomotive supplying the power does not form a patentable part of my invention, I have illustrated only a plow which carries its own engine, it being understood that any style of engine may be employed which may be found practicable.

In the accompanying drawings, .in whichi similar letters of reference indicate like parts, Figure 1 is a central longitudinalsection ofaj railway snow-plow and track-clearer embodying my invention. Fig. 2 is. a section taken Fig.3 is a longitudinal vertical section on line y, Fig. 2. Fig. 4 is a transverse vertical section on line .2, Fig. 1.

A represents the flo0r,A and A the side walls, and A the roof,.of the carriage supporting the plow.

a a are the wheels, a is the track, and B is an engine of any suitable type situated in thie) rear portion of the carriage. B is .the ca C O are two large wheels placed side by side at the forward end of the carriage, whose hubs C are fast to the driving-shaft C. This shaft has its bearings in suitable arms 0, bolted to the sides A and A. The shaft, and of course the wheels 0, are rotated by means of the cranks (Z, to which power is supplied from the engine B by means of the steam-pipes B, steam-chests b, and pisto11- rods 19. A

D is a cylinder extending from one to the other of the wheels C and rigidly secured to their peripheries. 7

E E are the clearers firmly bolted to the cylinder D. These clearers may be of any desired number, and are each of the shape shown-2 e., trough-shaped-that is to say, in

cross-section of the shape of an arc of a cir cle and bent into an inverted-V shape longitudinally, with the apex at the longitudinal center of the outside of the cylinder. The clearers are all alike in shape and position, so that a central circumferential line on the cylinder would touch the apexes of all the clearers. From the roof A the carriage drops at F, thus closing the front to a point just above the path of the cleaners as they revolve, and a curved partition II extends from the front F (see Fig. 3) around the path of the revolving clearers until it reaches and is socured to the bottom A. This partition is continuous at its portions next the sides A A, (see Figs. 2, 3, and 4,) but is provided with a broad central opening H from its upper end nearly to its lower end. (See Figs. 1 and 2.)

I I are longitudinal vertical parallel partitions extending from the front F and from the curved partition II next the opposite edges of its central opening H rearward, as shown. (See Figs. 1, 2, and 4.)

J is a partition, horizontal in cross-section, extending from the front portion of the under side of the roof A rearward and downward, as shown in Fig. 1, between the partitions I I. J is the. rear end of said partition, which connects the roof portion J with the floor portion J (see Figs. 1 and 2,) said floor portion being preferably depressed at its center J and extending forward to meet the lower edge of the passage or opening 11' in the partition H. The portion J extends forward at J into a V shape, as shown in Fig. 2, for the purpose below described.

K K are partitions, horizontal in cross-section, situated between the vertical partitions I and I and the sides A and A. Each of these partitions has one of its horizontal front edges joined to the curved partition H between the opening II and the side of the carriage, and extends downward and sweeps round in a circle, as shown in Fig. 3; thence at K doubling back upon itself and curving forward at K on a line substantially concentric with the line of the partition H, and with its front edge 'joining at the point shown the roof A L is a shaft having its hearings in the vertical sides of the V-shaped portion J of the partition J. This shaft extends through the annular openings 1 in the partitions I and I (see Figs. 2 and 3) into the chambers formed by the annular portion of the partitions K, and has rigidly secured to it the fans Z. Rotary motion is imparted to the shaft, and' hence to the fans, by means of the crank L, power being applied thereto from the engine 13 by means of the steam-pipe O, steam-chest O, and piston-rod O.

N N are twin outlet-pipes extending from the roof A near its side edges and front edge. These pipes are provided with elbow-joints N, adapted to be rotated so as to be turned in any desired direction, reference being had to the direction of the wind. The pipes N pierce the roof between the upper horizontal edges of the partitions K and the front of the carriage. The sides A and A are provided, respectivelyavith inlet-openingsP and P. (See Figs. 1, 2, and 4.) These openings are not coincident, (see Fig. 2,) the opening P being situated at a point farther to the rear than the opening P. Both openings pierce the sides between the partition H and the path of the cylinder D. In other words, they open directly upon the path of the rotating clearers.

The wheels 0 C, the cylinder D, and the fans Z having been set in motion by the means above described, the clearers E revolve and lift the snow from the track and carry it over the cylinder through the wide passage or opening H to the floor J Thence the mass is separated into two parts, passes through the openings 1' into the round chambers formed by the plates K, where it is caught by the fans Z and carried up the passages between the plate H and the plates or partitions K, from which it passes into the pipes N and elbowjoints N and outside, the direction of its throw being dependent upon the direction in which the elbow-joints are pointed. Air is supplied to the interior through the side openings P and P, and as each clearer passes over the center an air-space is formed between the central outer edge of said clearer and the upper edge of the opening H. As the side openin gs P and P are not placed exactly opposite each other, in practical operation the air enters the side openings and the opening H not simultaneously, but one after another, thereby causing the flow of air to be more efficient and lessening the danger of clogging.

In order that the track may be cleared of snow or ice next the inner sides of the rails,

thus providing a passage for the flanges of the wheels, I have provided a shaft R, rigidly secured to which are cutters S, whose teeth extend down next the inner sides of the rails. This shaft is rotated by means of the crank R, to which motion is imparted from the engine by means of the piston-rod t, steam-chest t, and steam-pipe t.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. The trough-shaped clearers E, of the inverted-V shape shown, in combination with the cylinder D and wheels C O, substantially as and for the purpose set forth.

2. The combination, with the clearer-s E, cylinder D, and wheels G C, of the partition H, extending from the front piece F rearward outside the path of the clearers and provided with the central opening H, substantially as and for the purpose described.

The combination, with the carriage, of the partition H, provided with the opening H, the roof portion J, floor J, V- shaped ver tical portion J J and partitions I I, substantially as and for the purpose set forth.

4. The combination, with the carriage whose sides A A are provided with the openings P P, of the partitions I I, provided with the openings 1, fans 1, provided with means whereby they may be rotated, partitions K K, of the shape shown, partition H, and pipes N N", substantially as and for the purpose doscribed.

'the cylinder D, wheels 0 O, and clearers E,

the partition H, provided with the opening H, centrally-depressed floor J, V-shaped partition J J, roof J, partitions I I, provided with the openings 1", fans I, partitions K K, and pipes N N, substantially as and for the purpose described. r
